What do Anti-Lock Braking Systems (ABS) do in a vehicle?

1. Reduce braking power

2. Are equipped in addition to other braking systems

3. Replace conventional braking systems

4. Increase stopping distance

The correct answer is: Are equipped in addition to other braking systems

Anti-Lock Braking Systems (ABS) are designed to enhance vehicle safety during braking, particularly in emergency situations. They do this by preventing the wheels from locking up during hard braking, which helps to maintain steering control. The correct answer highlights that ABS are equipped in addition to other braking systems, not as a replacement for them. Ultimately, ABS works alongside traditional braking systems to improve the vehicle's overall braking performance, especially on slippery surfaces. This design allows drivers to brake more effectively without losing control, which can significantly reduce the risk of accidents. In contrast, the other options are misleading. For instance, ABS does not reduce braking power; instead, it helps manage braking force for better control. They also do not replace conventional braking systems, since conventional brakes are still essential for stopping the vehicle effectively. Furthermore, ABS does not increase stopping distance; rather, it typically helps to shorten stopping distances in tricky conditions by preventing wheel lock-up.
